Wall Street Journal reporter Justin Lahart spotlights the work of Prof. David Autor, an economist whose “thinking helped change our understanding of the American labor market.” Harvard Prof. Lawrence Katz says Autor has “probably been the most insightful and influential scholar of the labor market” in decades. “To me, the labor market is the central institution of any society,” says Autor. “The fastest way to improve people’s welfare is to improve the labor market.”
Katie Rae, CEO and managing partner of the Engine Ventures, speaks with Boston Globe reporter Aaron Pressman about The Engine Ventures’ third investment fund, which remains focused on “helping early-stage startups develop and commercialize ‘tough tech,’ which can include anything from fusion power generators to cement made without fossil fuels.” Rae notes: “You see this dynamism not just for climate, but for all things manufacturing, whether it’s biotech, whether it’s AI chips, it is about as an exciting moment as you could get for what we do.”
MIT scientists have discovered that metals become harder when heated under certain conditions, reports Isabelle Dume for Physics World. In an interview, Prof. Christopher Schuch says by bombarding metals with tiny bits of sapphire small enough to avoid shock waves, “the result is a clean and quantitative set of data that clearly reveals the counterintuitive ‘hotter-is-stronger’ effect.”
A new study by MIT engineers finds that heating metals can sometimes make them stronger, a “surprising phenomenon [that] could lead to a better understanding of important industrial processes and make for tougher aircraft,” reports Karmela Padavic-Callaghan for New Scientist. “It was just so unexpected or backwards of what you might conventionally see,” explains graduate student Ian Dowding.
Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '21 co-founded AgZen, an MIT spinoff that is developing new technologies to improve the performance and effectiveness of pesticide treatments, reports The Economist. The new technologies “could reduce the total amount of fungicides and insecticides sprayed over complete crops by some 90%, as well as cutting the amount of adjuvants required,” writes The Economist.
Writing for The Washington Post, Brian Deese, an MIT innovation fellow, lays out a framework for responding to China’s focus on increasing manufacturing. “The United States should send a clear message that the world will not absorb the costs of these distortionary policies,” Desse writes, “and should work with our allies toward a more durable framework for global growth.”
Prof. David Autor speaks with PBS host Walter Isaacson about the fear surrounding AI’s impact in the workforce and his view that AI could provide new opportunities for middle class workers. “Most of the time, technology is good for the elite and not so good for everybody else,” says Autor. “[AI] is a case where the technology might compete a little bit more with the elite and enable more people to do valuable work,” resulting in higher wages and more job opportunity for the middle class.
Fast Company reporter Shalene Gupta spotlights new research by Prof. David Autor that finds “about 60% of jobs in 2018 did not exist 1940. Since 1940, the bulk of new jobs has shifted from middle-class production and clerical jobs to high-paid professional jobs and low-paid service jobs.” Additionally, the researchers uncovered evidence that “automation eroded twice as many jobs from 1980 to 2018 as it had from 1940 to 1980. While augmentation did add some jobs to the economy, it was not as many as the ones lost by automation.”
Prof. Pulkit Agrawal and graduate student Gabriel Margolis speak with The Economist’s Babbage podcast about the simulation research and technology used in developing intelligent machines. “Simulation is a digital twin of reality,” says Agrawal. “But simulation still doesn’t have data, it is a digital twin of the environment. So, what we do is something called reinforcement learning which is learning by trial and error which means that we can try out many different combinations.”
Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”
Prof. David Autor speaks with Wall Street Journal reporter Jason Douglas about how there may be another “China shock” due to the influx of goods manufactured in China being made available in foreign markets. “It won’t be the same China shock,” says Autor, adding that “the concerns are more fundamental” as China is competing with advanced economies in cars, computer chips and complex machinery.
Former postdoc Leah Ellis speaks with GBH All Things Considered host Arun Rath about Sublime Systems, an MIT startup she co-founded that aims to produce carbon-free cement to combat climate change. “Sublime Systems and this technology spun out of my postdoctoral work at MIT,” says Ellis. “My co-founder and I are both electric chemists, so we have experience with battery technologies and electrochemical systems. Our idea was thinking about how we might use renewable energy—which we know has become more abundant, inexpensive and available—to eliminate the CO2 emissions from cement.”
Writing for Financial Times, economist Ann Harrison spotlights research by Prof. Daron Acemoglu, Pascual Restrepo PhD '16 and Prof. David Autor, that explores the impact of automation on jobs in the United States. Acemoglu and Restrepo have “calculated that each additional robot in the US eliminates 3.3 workers” and that “most of the increase in inequality is due to workers who perform routine tasks being hit by automation,” writes Harrison.
Researchers from the MIT Self-Assembly Lab have developed a 4D-knit dress that uses “heat-activated yarn that allows its shape and fit to be altered in an instant,” reports Rima Sabina Aouf for Dezeen. Prof. Skylar Tibbits notes that by having “one dress that can be customized for fit and style, it can be perfectly tailored to the individual while being more sustainable and adaptable to changes in season, style or inventory.”
A more than $40 million investment to add advanced nano-fabrication equipment and capabilities to MIT.nano will significantly expand the center’s nanofabrication capabilities, reports Jon Chesto for The Boston Globe. The new equipment, which will also be available to scientists outside MIT, will allow “startups and students access to wafer-making equipment used by larger companies. These tools will allow its researchers to make prototypes of an array of microelectronic devices.”
